As of 2015, apple-cider vinegar has not been proven to lower cholesterol, but those who attempt it use 2 teaspoons in a cup of water every day, according to WebMD. Apple-cider vinegar should always be diluted as the acid may harm tooth enamel at full strength.
There have been animal studies that show apple-cider vinegar use may help to lower blood pressure and cholesterol, claims WebMD. It also may slow cancer growth. However, as of 2015, this research is only in early stages, and no studies have been done on people to determine if similar results may be found.
There have been a number of other studies that show apple-cider vinegar may lower blood sugar, too, which could be beneficial for those who have diabetes, explains WebMD. Apple-cider vinegar also shows evidence in studies that it may make a person feel more full, which could be important for weight loss. Though there are no clinical trials to support using apple-cider vinegar for high blood pressure, vaginitis, skin health and general detoxification, people also use apple-cider vinegar for these conditions. However, when used for the long-term, apple-cider vinegar may lower bone density and alter blood sugar levels, so those who have osteoporosis or who are diabetic should use caution when taking it medicinally.
